I have some MKVs that for some reason will not display subtitles through PS3 Media Server. Subtitles do work most of the time, there's just something about these particular MKVs.I'm using PS3 Media Server 1.70, with Mencoder transcoding. I'm running Windows 7 32-bit with 4GB of RAM, 2.66GHz Intel Core 2 Duo processor. I've been trying this with a PS3, but I also have an Xbox 360. I tried on the xbox too, and still no subtitles for these MKVs.

Also, if it adds any light to the matter, I've had issues trying to demux these mkvs via mkvtoolnix for closer examination. I eventually managed to demux the video,audio, & subtitle tracks, but the TTF fonts that were embedded in the MKV still won't demux.
